查询当前 API Key 的调用配额，包括 read/write/write_note 三类的日/月剩余次数。
AI agents call get_quota to retrieve information from GetNote MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns quota/usage statistics for an API key. It performs no mutations, deletions, or external operations—it merely retrieves informational metadata. This is a classic Read category tool with minimal security impact if misused by an AI agent.
From the tool's definition Tool name is 'get_quota' and description states '查询当前 API Key 的调用配额' (query current API Key call quota), which is purely a retrieval operation with no side effects. It returns read/write/write_note quota information.
Documented attack patterns abuse exactly the kind of access get_quota gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GetNote MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_quota:
{
"version": "1",
"default": "deny",
"tools": {
"get_quota": {}
}
}get_quota is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the GetNote MCP Server MCP server in PolicyLayer and add a rule for get_quota: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GetNote MCP Server. Nothing to install.
get_quota is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_quota rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_quota. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_quota is provided by the GetNote MCP Server MCP server (iswalle/getnote-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GetNote MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
